LUBRICATING CAR-AXLES.

Specification of Letters Patent No. 21,652, dated October 5, 1858.

To all whom it 97? (Ly concern:

Be it known that I J onx V. COCHRAN, of the city, county, and State ofNew York, have invented a certain new and useful Improvement inLubricating Car-Axles; and I do hereby declare that the following is afull, and exact description thereof, reference being had to theaccompanying drawings and to the marks and letters thereon, like lettersand marks referring to like parts in all the figures thereof.

Of the drawings Figure 1, is a longitudi nal section taken as indicatedby the dotted lines in Fig. 2. Fig. 2, is an end cross section taken asindicated by the red dotted lines in Fi 1, and Fig. 3, is a verticalsection, taken at one side of the axle, showing the interior of the boxwhen in working condition.

(a, 0 marks the car box; (6, b) the axle; (c, 0) the lubricating wheelor rotary feeder, which, it will be seen very nearly touches the sidesof the opening in the diaphragm, thus controlling or limiting thequantity of fluid fed by the wheel from the well or chamber to the axle;(d, d) fiat spring to support the lubricating wheel or rotary feeder andkeep it up to the axle; (e, 6,) the well or chamber to contain thelubricating matter, either oil, water or whatever may be used in aliquid form. In the construction of this well or chamber full provisionis made for retaining the lubricating liquid and preventing wastage bythe swashing caused by the motion of the cars.

(g, g) marks the diaphragm, which forms the upper part of the well orchamber, and is so constructed and arranged as to be easily removed andadjusted at any angle to suit the size of the axle. It is made with theouter end lower than the inner or Wheel end, and any surplus liquidcarried up by the feeder will flow back to the well, passing through theopening for the spring and wheel at the front end; thus wastage isprevented at the opening where the end of the axle is passed into thebox, which joint itis impossible to keep tight, perfectly, for anylength of time. This plan will, in a great measure, do away with thenecessity of making the box very tight.

(/1, 72,) marks blgass or Babbitt metal. The red lines (2', 2') indicatethe hole made through the entire length of the axle, which should befilled with some good non-conducting material to assist in keeping thebearings cool. The boxes can be made with cells which can, also, befilled with like material and thus aid in preventing excessive heat.(7") screw-cock closing the opening for cleaning out the well; (j) spoutfor supplying the well with lubricating material; cover or door to thefront of the box.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patentis- In connection with the spring and wheel,the inclined diaphragm (g), having the space for the play of the wheeland access to the wheel and spring, as herein described.

Signed and witnessed at the city of New York this 9th day of July 1858.
